Shaft Wall

Telling C-T Shaftwall Framing Components

The two primary framing components in Shaftwall framing is the liner board (Example: DensGlass Ultra Shaftliner)  and C-T Studs and J tracks, manufactured by Telling™ Industries from galvanized steel that meets the requirements of ASTM A 653 and A 924.

The 2-1/2” steel framing system retains the popular 3-1/2” wall thickness with a two-hour fire rating to accommodate standard door framing dimensions. The Series 620 stud offers a unique feature — slotting in the web of the stud. Tests have demonstrated that these slots effectively improve resistance to thermal and noise transmissions.

The 2-1/2” stud provides a 1-1/2” air cavity for services. Studs are friction-fitted between top and bottom J- tracks. Use J tracks for all closure details, including duct and door openings, abutments, intersections, etc. No other special metal components are required.

The data relating to fire- and sound-tested assemblies is based on the characteristics, properties and performance of materials and systems obtained under controlled test conditions as set forth under the appropriate ASTM standard, such as E 119 (fire),
E 90 (sound) or E 72 (structural).

Building Code Compliance
Georgia-Pacific Gypsum shaftwall/stairwell enclosures meet the requirements of building codes of major jurisdictions throughout North America.

Easy Installation
Because shaftwall assemblies are built from one side only, there’s no need to access the inside of the shaft. The Telling™ C-T Stud and J-Track steel framing members go up quickly. Most configurations require only two steel components and two types of gypsum board. That makes our systems ideal for furred chases and interior partitions where fire ratings are required for exterior walls and access is restricted.

Engineered for durability, our systems withstand the air-pressure surges of high-speed elevators as well as the lateral impact of stairway doors.
